Answer:
The weights of all elements are always compared to the Carbon-12.
Explanation:
The weights of all elements are always compared to the Carbon-12 because the mass of carbon is 12 which is the exactly the sum of protons and neutrons.
Oxygen was also considered the standard for some time but later this stander was rejected because in natural O¹⁷ and O¹⁸ were also present and this create the two different atomic mass tables.
AMU:
Atomic mass unit is define as the 1/12 the mass of an atom of carbon-12.
C12 has six neutron and six protons in the nucleus.
This unit is used to express the masses of atoms. We know that masses of atoms are very small and we do not have any such type of balance that can measure very small quantity. So that is way we use this scale to measure small quantity. For example, according to this scale
relative atomic mass of hydrogen is 1.008 amu
relative atomic mass of oxygen is 15.999 amu
relative atomic mass of uranium is 238.0289 amu
relative atomic mass of chlorine is 35.453 amu
Answer:
In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total 2 xx (1-) = 2- net charge. Therefore, you are dealing with an anion that carries a 2- net charge, i.e. it has two more electrons than it does protons.
There are certain rules to follow when naming covalent compounds. But first, let us look at the definition of Covalent Compounds.
<h3>
What are Covalent Compounds?</h3>
When covalent bonds aid the creation of a molecule, in which the atoms have at least one similar pair of valence electrons, a covalent compound is said to have been formed.
A very common example is water (H₂O)
<h3>
How are Covalent Compounds named?</h3>
To name a covalent compound, simply list the first element in the formula using the name of the element, then name the second element by adding the suffix "ide" to the stem of the second element's name.
If there is only one atom in the molecule of the first element, then no prefix should be added.
It is to be noted that if the second element in the compound is oxygen, then we should say:
- monox<em>ide</em> instead of monoox<em>ide</em> and
- triox<em>ide</em> instead of trox<em>ide</em>, all depending on how many atoms that are involved.
See the attached for the prefixes related to the various number of atoms in the compounds.
It is to be noted that the covalent compound to be named here is not stated hence the general answer.
